Pete eliminated 4 of the transistors out of the
original circuit ( Above Right ) and then re-engineered those
portions selecting a CA3046 Integrated Circuit chip shown on the left. This in my own
opinion, would solve a lot of production problems, as well as provide a faster way to
repair this unit. Based upon past experience the components that usually fail tend to be
the active ones, the transistors. Using this design one would only have to swap out the
chip, which would take less than a minute rather than returning it to the source for
repair, and could be conducted in the field by anyone.
